It took me several weeks of weening. I didn't intend to quit smoking, though. It just happened that after about 3 weeks, I walked around for a full week with an open pack without lighting one. At the end of that, I said to myself, "I must not be a smoker anymore!"
Congratulations on your success so far! I encourage you to continue
vaping like you're trying to break the thing if you need to. The urge may come that is unbearable. If you find yourself lighting a cigarette, don't beat yourself up about it. Take pride in all the cigs you've avoided and know that when you're done, the e-cig holds no animosity in your weak moment and will happily continue to perform without judgement.
You're on the right track and it's a path with many great people to hold your hand.
